This is what you want it to do… as quickly as possible!!! The intent is to have a falling mass propel a cart carrying an egg down a track as quickly as possible and end up with the egg as close to the center of the terminal barrier without… Scrambler 2014 DRAFT
DOING THIS!!! Now you know why it is called SCRAMBLER.... or in this case SUNNY SIDE UPPER!! Scrambler 2014 DRAFT
You Tube Views Like this..... ....or better like this!!! Those were from a few years ago, and a number of things have changed, so let’s get cracking! Scrambler 2014 DRAFT
Construction Scrambler 2014 DRAFT
Construction Entire device – Maximum: 1.00 m high, 0.75 m wide and 1.00 m long Could be 1 or 2 parts ALL energy from a falling mass – 2.00 kg max (GPE & KE) Must start with a #2 pencil Stopping mechanism built in No electricity/electronics Egg: large, grade A Provided by event supervisor Foremost part of vehicle Taped to the following….. Scrambler 2014 DRAFT
Approximately 10-15 cm long, must break laser beam at 25 cm above floor f f ¼” dowel for Photogate Backstop Backstop Dimensions: 5 cm x 5 cm x 0.5 in ¼” dowels for egg support Distance to bottom of dowel from floor MUST be between 5 and 10 cm.
Terminal Barrier Distance The Track Timed Distance Center Line Center Point Caution: This diagram is NOT in proportion. The track width is only 1.5 m wide. Starting Line Terminal Barrier Terminal Barrier Distance 8.70 – 11.70 m 1.0 m inc: Regionals 0.5 m inc: States 0.1 m inc: Nats 0.2 m Line 8.2 m Line Scrambler 2014 DRAFT
Competition 10 min. to do 2 runs Tip of egg even with starting line, anywhere along it All parts behind starting line Start with pencil ONLY 1 egg allowed – if broken on first run, NO second run! Alignment Scrambler 2014 DRAFT
Scoring Time Score: 5 x Run Time (Run Time is the time to travel between 0.2 and 8.2 m lines.) Distance Score: Distance from the pointed end of egg to centerline of the terminal barrier (cm) Run Score = Time Score + Distance Score Whatever run gives you the best ranking is the one counted Tiebreakers Scrambler 2014 DRAFT
Penalties Run penalties (Tier 2) Egg broken ANY part of egg transport contacts wall besides egg Transport runs outside lane (at ANY time) Transport doesn’t travel 8.20 m Transport passes terminal barrier (Tier 2 and score of 5000) Construction penalties (Tier 3) Ranked tiers Scrambler 2014 DRAFT

Building suggestions First and foremost, build early, practice, log, and calibrate as many runs as possible. Use a plastic egg filled with any material to around 65 g Always build just under/over the dimensions!!!! Make the transport as light as possible Perhaps try some different floor surfaces Did I say calibrate? Strongly consider using aligning devices since you need the transport to go as straight as possible Scrambler 2014 DRAFT
